NAME
Graphics::Primitive::Font - Text styling
DESCRIPTION
Graphics::Primitive::Font represents the various options that are available when rendering text. The options here may or may not have an
effect on your rendering. They represent a cross-section of the features provided by various drivers. Setting them should not break
anything, but may not have an effect if the driver doesn't understand the option.
SYNOPSIS
use Graphics::Primitive::Font;
my $font = Graphics::Primitive::Font->new({
family => 'Arial',
size => 12,
slant => 'normal'
});
METHODS
Constructor
Attributes
antialias_modes
Set the antialiasing mode for this font. Possible values are default, none, gray and subpixel.
family
Set this font's family.
hint_metrics
Controls whether to hint font metrics. Hinting means quantizing them so that they are integer values in device space. This improves the
consistency of letter and line spacing, however it also means that text will be laid out differently at different zoom factors. May not be
supported by all drivers.
hint_style
Set the the type of hinting to do on font outlines. Hinting is the process of fitting outlines to the pixel grid in order to improve the
appearance of the result. Since hinting outlines involves distorting them, it also reduces the faithfulness to the original outline shapes.
Not all of the outline hinting styles are supported by all drivers. Options are default, none, slight, medium and full.
size
Set/Get the size of this font.
slant
Set/Get the slant of this font. Valid values are normal, italic and oblique.
subpixel_order
Set the order of color elements within each pixel on the display device when rendering with subpixel antialiasing. Value values are
default, rgb, bgr, vrgb and vbgr.
variant
Set/Get the variant of this font. Valid values are normal or small-caps.
weight
Set/Get the weight of this font. Value valies are normal and bold.
METHODS
new
Creates a new Graphics::Primitive::Font.
derive
Clone this font but change one or more of it's attributes by passing in a hashref of options:
my $new = $font->derive({ attr => $newvalue });
The returned font will be identical to the cloned one, save the attributes specified.
